Spyderco 400F Ceramic File Set 5" Fine Grit - Leather Case

The Spyderco 400F Ceramic File Set is a compact sharpening system built around four fine-grit high-alumina ceramic files in a clean white finish. The ceramic rods are loaded with synthetic sapphire particles, giving them the hardness needed to deburr, refine, and finish hardened blade steel without stripping away excess material. They are an ideal finishing tool for touching up a working edge between heavier sharpenings or putting the final polish on a freshly ground profile.

The set covers the four most useful file profiles for detail work on blades and edged tools. A round file handles inside curves and holes, a square file cleans out square-bottom grooves and slots, a triangular file is shaped to ride through serrations and inside corners, and a slip (teardrop) file reaches into tight contours and lays down a clean draw-filed finish. Each file runs roughly 5" overall, long enough to work full-size blades yet compact enough to live in a shop drawer or range bag.

All four rods are fine-grit ceramic, intended for finishing and maintenance work rather than reprofiling an edge. The complete set ships in a suede leather snap-close pouch that keeps the files organized, protected, and ready to pull out at the bench or in the field.
